Problems solved by technology

However, compared with the bolt-supported roadway, the front beam of the anchor-cable-supported roadway is not easy to hang, and the exposed steel strands are easy to be damaged after blasting, causing the suspension device to be unable to withdraw; at the same time, the anchor of the fixed suspension device is the same as the original support anchor. The spacing cannot be effectively controlled, resulting in the anchorage of the fixed suspension device being unable to withdraw

Embodiment 1

[0028] A kind of full anchor cable support roadway temporary support front beam suspension device, such as Figure 1-Figure 3 As shown, the suspension device is in the shape of an inverted "L" and includes a vertical plate 1 and a horizontal plate 2. The horizontal plate 2 is provided with an anchor hole 3, and the top of the vertical plate 1 is provided with a threaded hole 4. The horizontal plate 2 The inner side is provided with safety baffle 5, and the length and width of safety baffle 5 are identical with transverse plate 2.

[0029] The length of described longitudinal plate is 15cm, and width is 10cm, and height is 50cm, and the length of horizontal plate is 25cm, and width is 10cm, and height is 10cm. The diameter of the anchor hole is 3cm.

[0030] In the present invention, the application of the suspension device of the probing beam before the temporary support of the full anchor cable support roadway, the steps are as follows:

[0031] After cutting the coal head-...

Abstract

The invention relates to a temporary supporting forepoling bar suspension device of a full anchor-cable supporting roadway and application. The device is characterized in that the suspension device isin an inverted L shape and comprises a longitudinal plate and a transverse plate, an anchor device penetrating hole is formed in the transverse plate, a threaded hole is formed in the top of the longitudinal plate, and a safe baffle plate is arranged on the inner side of the transverse plate, and the length and width of the safe baffle plate are same as those of the transverse plate; according tothe device, each forepoling bar utilizes two temporary supporting forepoling bar suspension devices of the full anchor-cable supporting roadway. The device is simple in manufacturing technology, flexible in operation and high in adaptability, it can be ensured that after coal cutting (blasting), the full anchor-cable supporting roadway can be effectively supported temporarily, by adopting the suspension device, an original anchor cable which has reached the pre-tightening state does not need to be dismantled, and it is avoided that due to dismantling of the anchor cable, anchoring fails, theempty roof phenomenon occurs again, and the roof falling accident is caused.

Description

technical field [0001] The invention relates to a full-anchor cable-supported roadway temporary support front beam suspension device and its application, belonging to the technical field of coal mining. Background technique [0002] In order to avoid the empty roof operation after coal cutting (blasting) in the excavation roadway, temporary support must be used to reduce the danger in the head-on construction. The anchor bolt supports the roadway and directly fixes the suspension device of the probing beam before the temporary support on the anchor rod. Convenient and adaptable. [0003] At present, the commonly used method of roof full anchor cable support uses anchor cables to replace the original anchor rods to support the roof, which has a good support effect and eliminates the phenomenon of repairing. However, compared with the bolt-supported roadway, the front probe beam of the anchor-cable-supported roadway is not easy to hang, and the exposed steel strands are easil...
